Cool start, warming trend ahead

Runners will face a temperature rise from 47°F at the start to a peak of 65°F by finish. Wind will be light, peaking at 9 mph with varying directions, but headwinds will hit from miles 11-17. The hilly terrain means runners should pace conservatively, especially on climbs, and hydrate frequently as humidity sits at 54%. No rain is expected, but a throwaway layer may be useful during the pre-race wait.
